Say what you want about the current spate of e-books, few will do anything to hold the interest of your three-year-old nephew. To those who like to keep peanut butter and jelly out of the keys if their Kindles that's a good thing, but for Barnes & Noble that's a business opportunity waiting to be tapped. According to The Wall Street Journal, the company will soon launch Nook Kids, a dedicated collection for young readers expected to start with an impressive selection of 12,000 titles. Many of those will be "enhanced," like the book Jamberry, having one page with falling blueberries that kids can pop with a tap. That seems to be further proof of a full touchscreen on the rumored Color Nook, expected to be unveiled this Tuesday. Later in the year look for a Nook Kids app on the iPad and other devices, so now might be a good time to start teaching little Joey about regular hand cleaning.
